Mapping the **this** pointer

Dear LLVM OpenMP 4.5 support.

I'm trying to map the **this** pointer of an class but I'm getting a
compilation error: 

repro.cpp:20:38: error: expected expression containing only member accesses
and/or
      array sections based on named variables
#pragma omp target enter data map(to:this)
                                     ^~~~
repro.cpp:27:41: error: expected expression containing only member accesses
and/or
      array sections based on named variables
#pragma omp target exit data map(delete:this)
                                        ^~~~
2 errors generated.

I'm attaching a reproducible for the error.
